In these project http://tools.webmasterei.com/countrymap/ the
polygones are added via ajax in a global array polygones[]:
After adding the polygone I like to detect clicks like in the app from
Mike W. (inside)
Here is the snippet:
==
var map;
var polygons = [];
var countries = Array();
var rules= {
'.country input' : function(el) {
el.onchange = function() {
var id = el.id.split('_');
new Ajax.Request('./kml.class.php?countryid=' + id[1] +
'&checked='
+ el.checked, {
method: 'get',
onSuccess: function(transport) {
eval(transport.responseText);
}
});
}
}
};
Event.observe(window, 'load', init_app);
Event.observe(window, 'unload', GUnload);
function init_app(event) {
Behaviour.register(rules);
Behaviour.apply(rules);
map = new GMap2(document.getElementById("map"));
map.setCenter(new GLatLng(15.507563, 10.797715), 2);
GEvent.addListener(map, "click", function(overlay,point) {
if (!overlay) {
for (var i=0; i<polygons.length; i++) {
if (polygons[i].Contains(point)) {
map.openInfoWindowHtml(point,"You clicked on ");
//i = 999; // Jump out of loop
}
}
}
});
}
==
In the callback appears after adding of one polygone the error
'olygons[i] is undefined'.
Any ideas?
